Propagation method of lily

1. The young bulbs of Lilium bulb should be cultivated continuously for several years and reach a certain size before they can be harvested and eaten. The bulbs used for sowing in the year of harvest are called bulbs.

The main results are as follows: 1) this method is suitable for varieties that can produce pearl teeth, such as Yixing lily, more than half of the leaves and leaf axils of Yixing lily can grow bulbs, and each plant can produce more than 40-50 buds.

2) the bulbs, namely bulbs, were cultivated with bulbs, which were born in the soil at the base of the aboveground stem. Many lilies can form balls, such as Lanzhou lilies, each lily can give birth to about 20, as many as more than 30. When harvesting lilies, the small bulbs are stored separately and graded according to the size of the bulbs. 30-50 grams of large bulbs can be directly used as seed bulbs to produce commercial lilies, and those less than 30 grams need to be cultivated. Generally divided into 20-30 grams, 10-20 grams and less than 10 grams, 20-30 grams weight bulbs, cultivated for 2 years can be used as seed bulbs, others need to be cultivated for 3 years to meet the seed ball standards.

3) scale breeding bulb is referred to as scale propagation method, scale reproduction method is the most commonly used in lily asexual reproduction, and the reproduction coefficient is also the highest. This method is most suitable for Longya lily, because it does not produce bulbs, it can also be used in Lanzhou lily. Generally, a piece of scale is peeled off and the temperature is kept at 80% Mur90%. Under 20-24 ℃, one or more bulbs can grow near the base of the wound after 10-15 days, the roots can grow at the base of the bulbs after 10-15 days, and the basal leaves will grow after about 30 days. Given certain light, temperature, fertilizer and other conditions, they can grow into small bulbs with a diameter of 1.2-1.5cm in 60-70 days. If you plant it in the field for another two years, you will be able to get seeds for commodity production. Scale reproduction methods generally have the following: seedbed cutting method: first of all, we should choose sandy soil with good drainage, loose and fertile, no onion, garlic and eggplant crops, and make a seedbed with a width of 1.3 meters and a height of about 25 centimeters, and the length depends on the topography. The cutting period is generally from August to September (in the south) and in the north after thawing in early spring. Indoor sand culture method: choose a house with cool and ventilated air temperature (about 20 ℃) and stable soil floor, first spread a layer of clean wet sand 5 cm thick on the ground, 1 meter wide, unlimited length, and then put a layer of scales to cover a layer of wet sand; a total of 5 layers, and then covered with 5 cm thick wet sand. Heap height of 25-30 cm is appropriate, not too high. In the future, according to the situation, evenly pour water on the sand pile (no water seepage at the bottom is appropriate), in order to keep moist. It usually takes about 15 days to grow a 3 cm long base. Within 1 month, it can be transplanted to the field seedbed with roots, together with scales and bulbs. Keep growing. Scale air culture technique: scale air culture is a cultivation technique in which the exfoliated lily scales are exposed to the air for artificial culture. after 60-80 days of indoor culture, the growth obtained after one natural growing season is equivalent to that of the two growing seasons of scale soil cutting, which can effectively shorten the growth cycle of flowering and harvest of lilies, and the bulbs grow well.

4) the seed core propagation method selects the plants with no disease, big bulb, white bulb, no disease spot, developed root system, clear petal and compact clasping. Generally speaking, each female ball of Longya lily is composed of 2-3 bulbs. When processing dry pieces, the daughter peels are separated, so that each daughter valve has a stem bottom disk and a root system, and the outer large scales of each daughter bulb are peeled off, leaving the seed core as the breeding material. Hide in sand over the summer and sow seeds after the autumn is cool.
